Ubuntu 22.04下NetBeans构建失败（提示release版本17不支持）

环境配置 #

• Java版本：17.0.6
• Ant版本：1.10.12
• 操作系统：Ubuntu 22.04.4 LTS

问题现象 #

构建NetBeans过程中失败，报错日志如下：

-do-compile:
  [nb-javac] Compiling 10 source files to /media/meca1/GITHUB-NETBEANS/netbeans/platform/api.dashboard/build/classes
  [nb-javac] Ignoring source, target and bootclasspath as release has been set
  [repeat] error: release version 17 not supported
  [repeat] Usage: javac <options> <source files>
  [repeat] use --help for a list of possible options
  [nbmerge] Failed to build target: all-api.dashboard

已尝试操作 #

• 首次使用JDK 17构建失败
• 执行export JAVA_HOME=/opt/jdk-11切换到JDK 11，问题依旧（NetBeans官方文档显示JDK 17兼容）

解决办法 #

• 确认Ant使用的JDK版本：执行ant -version，查看输出中的Java版本，确认Ant是否读取到了正确的JDK。
• 刷新环境变量：切换JAVA_HOME后，执行source ~/.bashrc（bash终端）或source ~/.zshrc（zsh终端），或直接重启终端，确保环境变量生效。
• 检查NetBeans构建配置：打开nbbuild/build.properties文件，找到jdk.home配置项，将其设置为正确的JDK 17路径（例如jdk.home=/opt/jdk-17.0.6），覆盖系统环境变量的设置。
• 清理构建缓存：执行ant clean命令清理之前的构建残留，然后重新执行构建命令。
• 验证JDK有效性：执行javac -version和java -version，确认输出为17.0.6，确保JDK安装完整且未损坏。
